Pneumatic spiral water pump



T. WESTGARD PNBUMATIG SPIRAL WATER PUMP sept. 2, 1930.

Filed March 21, 1929 Ver it eXtendsthrough the-apertureV 9 in which itis placed has threaded thereon a locking nut 12 whichv maintains thepipe inset position.

Secured to the lower. end of the compressed v air chamber is ajwaterscreen Vor cage 13 of the usual type into which the the intake pipe 6opens;

-In the upper portion of the intake pipe 6, that is, the portion 8 whichextends above the upper reducingcoupling 2, there is secured anelongated spiralediin 14 which consists oi a strip .of relativelyy thinmetal torsionally` twisted and secured at its edgesto the wall of the-pipein which'itfislplaced.

.. The upper end of the intake pipe 6 is suitjably threaded as indicatedatv '15 to facilitate the application thereto of one of a number of pipesections which make Iupy a wall cashing anduponl the lowerend of whichthe present ypump isdesigned toV be mounted. A

o The compressed air .line 5l may be provided iwith suitable control'valve such as that'inf dicated at 16 VVso1 that the introduction of airinto rthe compressed air chamber may be reg#V ulated at; will.

' f'lfromj the `foregoing description it will be `vfunderstoo'd that'byintroducing airunder jv ypressure into the water intake pipe'A section yareduced pressure willfbe createdaboutj the through the upwardlydirected.v jets therein,

intake screen, thus causing water surroundy ing' the 'same to enter andpass upwardly through thepipe 6.'- As the column ofwater ascen s throughthe pipe 6 and the pipe casingr` attached to the upper end thereof, arotary motion will be imparted thereto by the spiral lin 14, whichaction will ytend to fiurther increasethereduced air Vpressure orcondition of partial vacuum in the lower end 'K of the pipe and causethe; water to pass upwardly faster and smoother. jl o {,While thelengthof the spirallin 14 may p be o .fanynumber of inches desired, it is pre-*re'rred thatwhen using ,thesame in a pipe fof two and one-half inchesdiameter that a three-quarter twister turn bei given thereto v vforVeach eighteen; inches of length.

, v`while in the foregoing, i have described.

jthespiral-as being secured in the upper end 'ofthe waterintake pipe6,.it is apparent, of

" course, that if desired this spiral may be made al part of kaseparateplpe section or nipple vsuchas that `shown in Figure 4 andindicated by the numeral 17 V/Vhen the spiral .is pro- Y vvided'inthismannerthe nipple may be 'K ce readily applied or removed `fromthe upper ,end of the'pipesection 6 and the lower section o f the pipeline to rwhich the pump is attached will then .receive the spiral 18carried by the' i V'nipple and will be attached to the upper end ofthenipple as ywill be readily understood.

` .Y Ilclaim:- Y. l I l f 1.y A pneumatic pump comprising a cylindricalbody designed to be secured at the lower end of' -lower end of a wellpipe line and open for the vintake of fluid thereinto, a plurality ofjet Vtubes within and directed upwardly in the body, means forintroducing air under pressure to each otsaid )et pipes for dischargetherethrough into the body, and spiral means within the upper portion ofsaid body and positioned at lthe lower end thereof between a pluralityof jet pipes tor imparting a spiral motion to the uids passingtherethrough, said jetr pipes opening through the wall of the `,body anddisposed longitudinally and circumferentially 'thereof and dischargingair upwardly against said spiral means.

A; pneumatic pump comprising a tubular body open at each 'end andadapted to have one 'end secured to the lower end of a pump line pipe, aplurality of air jet tubes fdisposed-withtherbody at dierent elevationsand directed upwardly therein, each of said `jettubes at its lower endopening laterally through the body wall, means for introducing airunderv pressure to each of said jet tubes, and'spiralfmeans' within thebody and having 'the lower end thereof extended downn wardly of theupper ends of the upper of said jet tubes for imparting a spiral motionto iui'ds passing therethrough said jets discharging Vair upwardlyagainstA said spiral means. y

,3; 'A pneumatic pump comprising a tubular body open at each end andadapted to have one Vend secured to the lower end of a pump .line pipe,a plurality of air jet tubes l disposedwiththe body at differentelevations and directed upwardly therein, spiral means :have one endsecured to the lower end of a pump line pipe, a plurality of air jettubes disposed with the body at different elevations and 'directedupwardly therein, each of said jet tubes at its' lower' end openinglaterally through'the bodyjwall, a compressed air casing enclosing thatportion of the body having` the jet tubes opening therethrough,

.means for conducting air to the casing, anda .spiral element positionedwithin the body and lmounted at the lower end thereof between a pair ofsaid jet tubes designed to 1mpart ajwhirling motion to fluids passingtherethrough.
